Eerytime I cruz on the highway or street I keep throwing a p0172 code. I continue to drive my car and it goes off within a day or so. What does this mean and most importantly how can I fix what ever problem keeps settin off this code? Thanks

 

Dude i have the same problem i bought my own scanner because that code comes every day. let me guess is only comes on a low throttle and when your only babien your car. well thats when it comes on for me. but i REALLY!!!!!!! want to know how to get rid of the F'ing code to man hahaha

 

You took the words outta my mouth. My code came on this morn on the way to work I went to lunch and when I came back to work bam it went away. This is annoying ya kno. By the way are your tires 235mm on stock rims?

 

running rich heh?

 

Yea but my afrs r tuned perfectly. Its weird

 

bad o2 or sticking injector

 

I started gettin that code b4 I did any mods and I jus recently did 60 lb injectors so I don't think its the injectors. I'm catless so my post cat 02 is turned off. But if it was an 02 sensor y would it come on and off every now n then wouldn't it jus stay on?

 

ive replaced both o2 sensors cleaned MAF and the throttle body the dealer replaced my injectors so idk and yeah i have 235/40/r18's on the stock rims

 

Did you have any issues with the tire place getting them to put them on?

 

Lol he beat me 2 it. Did you notice if you hook up better with less spin? Does it rub at all when u make turns?

 

I have 235s on my Stock rim.. fit fine..

They only rub for me because i have a turbo convert.. so it rubs on the piping..

other wise youl be fine.

 

i put them on my self it took to bars with the tire machine to get them on but thats it. i dont get any rubbin and there was a noticable better differance with the hook up but the BIG differance in handling.
